Hubbard Glacier, Alaska Scenic Cruising

Almost every tidewater glacier in Alaska is retreating. Hubbard Glacier is the famous exception - a 76-mile river of ice that keeps growing, and occasionally surges, nearly sealing off Russell Fjord from the sea. On a Gulf of Alaska itinerary between the Inside Passage and the Anchorage-area ports, Hubbard is the marquee scenic day: a calving face miles across that fills Disenchantment Bay wall to wall. Where Tracy Arm is about the journey and College Fjord about the panorama, Hubbard is about spectacle - the thundering logistics of an ice age still in business.

Why Hubbard Glacier Keeps Advancing

Hubbard survives because of a quirk of geography: an enormous snow-catching basin high in the Saint Elias Mountains - one of the tallest coastal mountain ranges in North America - feeds it faster than its face can melt back. Glacier scientists describe the surrounding region as one of the snowiest places on earth. Hubbard also has a habit of rebuilding: it has surged forward several times in recent decades, damming Russell Fjord and creating a temporarily glacier-dammed freshwater lake before the tide broke through. When the face calves, blocks the size of buildings drop into the bay, and the sound of the splash arrives a beat after the crash. That is the moment you come here for.

The setting is wilder than most scenic waterways, too. Disenchantment Bay sits near Yakutat on the isolated Gulf of Alaska coast, far from any port, so the approach often includes wildlife that thrives around heavy ice: harbor seals resting on the floes, sea otters, bald eagles, and porpoises riding the bow wave on the way in.

Making The Most Of Your Scenic Cruising Day

Hubbard is the most visual-patience scenic day in Alaska - calving cannot be scheduled, so the experience rewards whoever stays positioned and keeps watching.

• Claim your viewing spot early: Hubbard draws a crowd to the open decks. The face is wide enough that you can see calving from almost anywhere with a clear sightline, but an upper open deck beats a window seat.
• Camera ready, drink warm: Calving is sudden and impossible to schedule. Burst shooting pays off - and a hot drink at the rail makes the wait comfortable.
• Dress warmer than the forecast says: Cold air rolls off the ice even on mild days, and standing off the face drops deck temperatures noticeably.
• Scan the whole face: Calving can happen at several spots along the six-mile front, so sweep wide rather than staring at one section. The ice that "goes" is often preceded by visible cracking and the squeak-moan of ice under stress.
• Watch the wildlife, too: Seals on the floating ice, otters in the flat water, and eagles riding the wind off the face are part of the show, not a sideshow.

The Ship You Choose Changes What You See

Any reasonably sized ship can stand in Disenchantment Bay and watch an active face calve - which is why Hubbard transfers well to big-ship itineraries, especially on one-way Gulf of Alaska sailings between Vancouver or Seattle and Whittier/Seward. Small-ship expedition operators that work this coast, including UnCruise Adventures and Lindblad Expeditions with its National Geographic fleet, get to spend longer in the approach and launch skiffs to move among the ice floes. On any ship, the captain holds a respectful distance from the face - out of caution and courtesy to the seals - and the naturalist commentary on a Hubbard day is some of the best in Alaska cruising.

Scenic Cruising Spots You Might Also Enjoy

Hubbard is one end of the Alaska ice-scenery spectrum; these five scenic days bracket what that means - from other glaciers to pure wildlife to tropical verticals.

• College Fjord, Alaska - The panorama answer: several tidewater glaciers visible simultaneously in Prince William Sound, named for East Coast universities by the 1899 Harriman expedition.
• Glacier Bay National Park, Alaska - The protected-park counterpoint: multiple tidewater glaciers including Margerie, with a National Park ranger aboard your ship for the day.
• Tracy Arm Fjord, Alaska - The journey version: a narrow fjord leading to the twin Sawyer Glaciers, iceberg-choked and dramatic on many Inside Passage itineraries.
• Na Pali Coast, Kauai, Hawaii - Where vertical rock replaces vertical ice: 4,000-foot emerald sea cliffs and sea caves, the tropical twin of the same rail-gripping idea.
• Frederick Sound, Alaska - If wildlife beats ice in your priorities: Southeast Alaska's densest summer humpback feeding ground, where scientists have documented bubble-net feeding since the 1970s.

The Glacier That Refuses To Retire

Hubbard is the Alaska scenic day that feels the oldest - ice behaving exactly as it did when the maps were drawn by guesswork. If an itinerary built around it appeals, our cruise specialist Heather Hills at Flow Voyages can match you to the Gulf of Alaska sailings that feature this day and the season that gives you the best calving odds.
